COVID 19 infection can cause long term damage to the brain and other parts of the body resulting in challenges, cognitive difficulties and emotional distress. The purpose of this study was to examine the tools that are utilized for evaluating health implications in individuals who have recovered from COVID 19 well, as the overall impact on mental wellbeing. The researchers conducted a review of studies published between January 2020 and April 2022 by searching databases such as PubMed, Scopus and ProQuest. A total of 20,166 studies was identified and Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) was used. The selected studies employed assessment instruments to evaluate health status among individuals affected by COVID 19. The Hospital Anxiety and Depression Scale (HADS) emerged as the used tool. Additionally, other scales were utilized to measure depression, anxiety levels, post-traumatic stress disorder (PTSD) and mental wellbeing. The findings from this review indicated that mental health issues and psychiatric symptoms persisted even after patients were discharged from hospitals. Several factors such as age, presence of comorbidities or underlying conditions ICU admission history, female gender involvement, and living in low income countries were identified as contributors, to anxiety disorders depression symptoms, and post-traumatic stress disorder (PTSD).
